All procedural, client-only, observe-only in PresentationSystemGroup, zero
netcode surface (read existing replicated state). Shared FeedbackFx decal
primitives (scorch blob + crack star meshes + transparent decal material).
ScorchDecalSystem: static RequestScorch queue -> pooled fading discs
(mirrors DynamicLightSystem), wired from the barrel boom, reusable by the
geyser. CoverDamageSystem: crack accretion keyed on BlightClutter.Remaining
(Variant 4) + proximity-gated shatter-scorch. RoomDressingSystem: persistent
arena scars on a distinct hash sub-stream, torn down with dressing. Knobs in
DecalConfig. Cover cracks use decals (not URPMaterialPropertyBaseColor) because
the Synty prop shader is not Hybrid-Per-Instance.

Operator feel report: the explosion radius was unreadable and the fuse
too short to react to. Two changes:
- Tuning.BarrelFuseTicks 36 -> 90 (~1.5s): long enough to READ the
danger and walk out, and better for baiting enemies onto a lit
barrel.
- WorldFeedbackSystem draws a pulsing ground DISC at exactly
Tuning.BarrelExplodeRadius under every lit fuse (keyed on the same
replicated Remaining=0-on-a-live-barrel cue as the boom split; one
shared pulsing material; removed via the existing prune path).
Verified live: disc appeared 0.07s after the pop (first fuse
snapshot), persisted to the boom at 1.54s, scale read exactly 3.25 =
the true detonation radius; 470/470 EditMode; console clean.

Phase 1.5 environmental hazard v1 (design-review wf_2cb10454-fdf: 13
findings confirmed + folded; Build Spec in the vault). ~25% of room
clutter seeds as EXPLOSIVE (Variant 3 on the existing replicated byte
- zero new GhostFields/prefabs/RPCs).
The FUSE is the review's fold - one mechanism closes both HIGHs:
- Pop sites (projectile sweep + isServer-gated melee harvest) do NOT
destroy an explosive: they zero the replicated Remaining + add a
server-only BarrelFuse (~36 ticks). The client sees Remaining=0 on a
still-alive barrel across snapshots -> unambiguous fuse cue, and
booms at despawn ONLY when cached Remaining<=0 - a teardown despawn
carries Remaining>0, so portal-advance teardowns can never fire
false booms (HIGH #1).
- HazardExplosionSystem (server, plain group, presence-gated on
BarrelFuse, never lifecycle-gated) detonates at ExplodeTick: radius
damage to LIVING enemies AND players (boss-slam player filter
verbatim; friendly fire = the bait mechanic), SourceTick stamped at
detonation = the authoring moment (HIGH #2: the authored-tick
contract dash i-frames negate against), SourceNetworkId=-1 (the
environment convention - a player id would consume Charger
whiff-punish windows). Fuse rides the RoomTag'd barrel -> teardown
cleans lit barrels free.
- Lit barrels are unhittable at both snapshot sites (no double-pop).
- Client: WorldFeedback caches Variant -> boom-vs-puff split (big
burst + light flash + boom SFX vs the old puff); DynamicLightSystem
gives Variant-3 barrels a red danger glow that STROBES once fused.
Verified: 470/470 EditMode (4 new: fused pop instead of destroy +
unhittable, both-sides damage w/ -1 source + authored tick, dead-player
+ radius filters, unelapsed-fuse inert); live smoke - seeded 3/8
explosive, real-sweep pop, CLIENT observed the fuse cue on the live
ghost, pinned bait enemy took exactly 26 (30->4), walk-out escape
confirmed; console clean.

New FeedbackFx static (MakeClip/MakeParticleMaterial/MakeBurst/PlayClip/EmitTinted/EmitAt); the 3 *FeedbackSystem copies + AmbientAudio.MakeSting now route through it via 'using static'. MakeBurst takes the FX-root + the per-use gravity/radius/sizeTail that were the only diffs between copies; MakeClip folds in noise + decay. Behaviour-identical by construction (every particle/clip param preserved exactly).
459/459 EditMode tests pass; compiles clean. VFX are presentation-only (no EditMode coverage) -> wants a Play-mode smoke to eyeball hit/death/harvest/structure bursts.

Rebuild the in-game HUD on UI Toolkit (HudUi/HudSystem, Aether palette) consistent with the menu; build-palette bar (BuildPaletteState) drives cursor->cell ground-ghost preview (green/red via BuildPreviewMath), left-click place / right-click cancel / rotate; fire suppressed in build mode; combat juice restyle. +4 BuildPreviewMath EditMode tests.
